I've contacted severalcustomers this week trying to see if any of them are being negatively affected by this. So far everyone is perfectly happy and have not noticed it being a problem. Joe, I never received an email from the one that posted on chasin game. I'm going to have time tommorow to run some test and plan to put 2 sg550's and 2 covert II's side by side and check em at differentdistances to see how big of a difference it is. I'll also run some test with blocking the sides of the pir. BMC has been in discussions with DLC's owner concerning the PIR. At this point with no extensive user feedback it's hard to know exactly what everone wants. What is easy to tell so far, everyone I know using this little camera is in love with it, especially it's performance in cold weather and battery life. Any concerns over diminished battery life due to the 2 additional led's have been eased. Everything I'm hearing tells me the camera gets as good if not better battery life than the Covert I.
